' My invention relates to a new-and useful "improvement in a coffee retainer' adapted for use with coffee urns in which thecoffee is placed ina retainer and the water poured thereover. WVith coffee urns of this class there is now commonly used a sack having 4 a ring along one edge to retain it indistended position and serve as a supporting member'for the-"sack. 'The water is then pouredinto the urn so as to pass over the coffee. On account'of the porous end of the sack, thewater isperm'itted to pass through the sack without being forced to pass over the coffeeso that a constant repouring of the water on'the coffee is required thus lesssuing the efficiency of the urn for making coffee. With a retainer of this classwhich is porous on itssides, the full strength of the coffee is not used as-all of the coffee vis not properly brought into contact with the water poured thereon. To overcome this objectionable feature is an object ofthe present invention inasmuchas the sides of the retainer being imperforate to the water, the water is forced, in order to pass into the urn, topass through the coffee itself which is placed in the retainer. 7

It has been found through experience that with the use of a coffee retainer such as the present invention embodies, thenecessity of repouring the water over the coffee is obviated. The coffee may also be ground finer on account of the very fine mesh of the sieve or screen member which is used with the retainer. \Vith the present invention it has been found that the amount of coffee bean necessary to produce a gallon of coffee may be reduced from eight to six or six andonehalf ounces, this saving in the amount of bean used resulting from the finer grinding and from the directing of the water directly through the coffee in a single pouring;

Another object of the invention is a provision of a coffee retainer which will be simple in structure, economical of manufacture and highly efiicient in use.

The efficiency and economy of the device results fronr the peculiar structure of the retainer. The cloth which is used as *a screening member or sieve may be of a very fine quality and of a close mesh. Although the cloth is of a poorer quality than the cloth now customarily used for coffee sacks an economy results in its use inasmuch as the I cloth may be quickly and easily Washed while in distended position so that while the washing is more thorough and the cleansing better, the; wear on the screen member is less. The ei'liciencyresults from thenon cloggingof thescreen member inasmuch as filter paper or perforated member will clog. @ther objects will appear hereinafter.

The invention consists in the combination and arrangement of described and claimed.- j a The invention will be'best understood from a reference to the accompanying drawings 'whichform apart of this specification. I Asshown in the drawings, [the urn with which the present invention is-used comprises a metallic cylindrical member 7 finsulated with a porcelain member 8. i

;ihe present invent-ion comprises a coffee retainer having imperforate side walls 9 made preferably cylindrical and slightly tapered inwardly at the lower end. The portion-ofupper wall 9 is provided with an outwardly extended flange '10 which is doubled upon itself at V the edge 11 and adapted to rest on the upper edge' of the memberS retaining the main body 9 slightly spaced over the inner. surfaces of the in sulatedmember 8. The lower end of the mainbody' 9 is curled upon itself to form a head '12 which projects inwardly of the main body'9, a slight flange beingprovided for-effecting this inward projection. The bead 12 is reinforced by a suitable wire 1?; projected therethrough. A ring 14 having an angularly turned inwardly directed portion 15 is adapted for mounting in the body 9, this ring 14 being inclined to the an gularly turned portion 15, slightly, to conform with the taper of the main body 9. A co-operative ring 16 tapered similarly to the ring 14 and having aninwardly projecting portion 17 is provided and adapted for engaging in and a very fine mesh.

When the cloth is being mounted between the rings 14 and 16 the cloth is stretched over the ring 14, and the ring 16 pressed firmly into the ring 14, the clearance beparts hereinafter tween these ringsbeing small so as to firmly Y clamp the cloth therebetween. By mounting .ii'l ter niountii'ig the cloth bet-ween the rings, the rings are then ineerted in the main body oi the container 9 as shown in Fig. 1, the head 12 serving to support these rings. It will be noted that the angularly turned portion 17 in considerably longer than the angularly turned portion l5. hen it is desired to remove the cloth, the user preesee the ang'ularly turned portion 17 with the thumbs while holding the ring 1-21: at its edge with the lingers.

When it is desired to clean the cloth 18 after use, the rings may be removed from the container 51 and the cloth l8 washed thoroughly while locked by the rings. The thorough cleaning oi the cloth 18 is etlecled by directing a stream of water through. it while in its taut condition. The collee oils tltllltlllllg' to the cloth 18 may be HilSO OZISll) and quickly removed by directing a stream of hot water through the ring or cloth 18.

The main body 9 is provided with a diametrically extended handle 19 which is socured at its opposite ends to the flange 10. As shown in Fig, :2 one side of the flange 10 is cut away as at .20 to provide a clearance :tor the in *ardly projecting water pipe which is used "for inrniehii ig the urn with water, this ater being directed through the collec;

1i desired, the rings ll and 16 may be dispensed with and a ring provided to clamp around the periphery oi? the lower end of the container so as to exteriorly hold: the cloth l8 in position. hen it is desired to remove the container from the urn, the handle 19 may be grasped by the user and quickly and easily removed from the urn. A lid 21 is provided for the urn in the usualnianner.

W'hile l have illufiilzlloil and described the preferred Form of structure I do not wish to limit myself to the precise details of etrricture set forth but deeii'e to avall my welt? oi? such variations and l!1(J(.l1llCtll;l()]1S as A coli'ee retainer of the class described adapted :for use withroti'ee urns comprising: an in'iperferate sleeve :lorniing member; supporting; means on the upper end (it said sleeve forming: member adapted for engaging said urn and supportingRaid sleeve therein; an inwardly projecting ,i'lange on the lower end otsaid sleeve, said flange being cnrled to form an inwardly ollset head; a clamping ring having an inwardly directed flange at its lower end, said flange being adapted for resting on the uppersurface of said beadedflange of said sleeve; a (o-operating clamping ring adapted for positioi'iing within said first niei itioned clan ip inc; ring; an inwardly directed flange on said cooperating ring; Said flange being oi greater length than, the flange on said first mentioned clamping! ring; and aporous nieniber clamped between said rings and extending across the opening thereincfor forining a eloeure tor the lowerend of said sleeve.
